GEARING FOR LAUNDRY MACHINERY.

Specification of Letters Patent.

Patented May '7, 1912.

To all whom it may concern:

Be it known that we, ANDREW TENSEN and FRANK VoNoRAsnK, citizens of theUnited States, residing at Chicago, in

the county of Cook and State of Illinois,

have invented new and useful Improvements in Gearin for LaundryMachinery, of

which the following is a specification.

This invention relates to gearing for laundry machinery, of that classemploying a stirrer for agitating the clothes within a tub, and having afly wheel for facilitating the work. I

One of the objects of this invention is to provide operativeconnections, between the stirrer shaft and a fly wheel locatedunderneath the tub, havin a construction whereby the lid of the tub maybe raised withoutdisturbing any of the elements of said connections, andin which the'lid may be raised from its closed position regardless ofthe position of the elements comprising the operative connections.

Another object is to provide gearing between the stirrer shaft and amotor driven fly wheel located underneath the tub whereby the mechanismmay be driven by power or by hand as desired.

Another object is to provide operative connections between such gearingand an auxiliary laundry device carried by the-tub,

as for instance a'wringer, mangle orthe like.-

Other objects and advantages will appear in the course of thisspecification and to such ends this invention consists in the severalnovel features of construction and arrangement set forth in thefollowing specification and particularly pointed out in the claims ;v e

In the drawings furnished herewith, Fig- 40 me 1 is aside elevation ofmechanism embodying the present improvement ina washing machine andwringer, Fig. 2 is a view partly in plan and partly in horizontalsection, the line of section being indicated at 2-2 Fig. 1, and Fig. 3is a plan of the upper elements of the gearing andv a fragment of thelid, and wringer.

Referring to said drawings 10, represents a tub carried by legs 11, andhaving a lid 12, hinged to the top of the tub and locked B. Cnnrsthereto in accordance with the common practice, A vertical stirrer shaft13,.carrymg a stirrer 14, is journaled in a frame 15, on the lid andprojects down into the inter1or of the tub as is customary The frame 15,is secured to the lid of the tub and has two upwardly extending bracketsin which is journaled a rock shaft 16, that carries upon its inner end abevel pinion 17 meshing with a bevel pinion 18, secured to the top ofthe stirrer shaft 13. Mechanism is provided for rocking the rock shaft16, one form of mechanism comprising; as shown, a rocker member 19,havinga gear segment 20, that meshes with a inion 21, fast upon theouter end of the roc shaft 16. It is obvious that by rocking the rockermember a rotary reciprocal movement is imparted to the stirrer shaft.Said rocker member 19, is fulcrumed upon a frame 22, secured to the sideof the tub, and if desired, may be formed with a handle socket 23,arranged to receive a handle 24, by means of which the rocker member maybe worked by hand. To facilitate the work, a fly wheel 34, is provided,and between said rocker member and fly wheel are operative connections,including speed increasing gearing, whereby the movements of the rockermember may be transformed into a continuous rotary movement of the flywheel at a comparatively high rate of speed. The particular form ofoperative connections shown between the rocker member and fly wheel willnow be described. A bevel gear wheel 26, carried by a shaft 27,journaled in a bracket 22*, of the frame 22, is connected to therockermember 19, by a link 28, as shown, whereby the rocking motion ofthe rocker member may be transformed into a continuous rotary movementof the bevel gear wheel 26, and reversely the rotary motion of the bevelgear wheel may be transformed into a. rocking motion of the rockermember. Said bevel gear wheel 26, meshes with a bevel pinion 29, fastuponthe upper end of a ver-.

tical, rotary shaft 30, ournaled in brackets 31, 32, formed upon t eframes 22, 33, respectively. The frame 33, is located below the tub andis secured to the legs 11, thereof.

The fly wheel 34, is journaled upon the .underside of the frame 33, andis operatively connected with the rotary shaft 30, by mechanism hereshown as comprising a small belt pulley 35, secured upon the shaft '36,of the fly wheel 34, a larger belt pulley 37 fast uponv the rotary shaft30, and a belt 38, trained around said pulleys. For convenience,construction and arrangement, we

have placed the frame 33, between the pulley 35, and fly wheel 34, saidpulley resting upon the frame and supporting the fly wheel therebelow.

In the operation of the machine thus far described, the rocker member 19is rocked back and forthby hand, whereby a rotary reciprocal movement isimparted to the stirrer shaft and a continuous rotary movementisimparted to the bevel gear wheel 20 rotary shaft 30, at a comparativelyhigh 26; said bevel gear wheel in turn drives the rate of speed, byreason of the difference in size between the bevel gear wheel andpinion, and the rotary shaft 30, drives the fly wheel 34, at a high rateof speed, whereby energymay be stored up by reason of the momentum ofthe "flywheel, and said energy,

utilized until spent, in operating the stirrer shaft. l

Power mechanism is provided fordriving the gearing and as 'shown oneform of power mechanism comprises an electric motor 39, secured totheunderside of the.

turn, will betransmitted to the stirrer shaft,

through the instrumentality of the vertical rotary shaft 30, theconnections between the fly wheel and said shaft 30, and the connectionsbetween said shaft and the stirrer shaft. The mechanism heretoforereferred to as the speed increasing gearing now becomes a speeddecreasing gearing and said I gearing will be hereafter termed as speedconverting gearing.

An auxiliary device 41, such as a wringer, mangle or the like, iscarried by the tub 10, and may be operatively connected to the gearingof the washing machine. As shown in a companion application for gearingfor laundry machinery, Serial Number 621,734, filed on even dateherewith, the shaft 27, of the gear wheel 26, bears a pinion 42, thatmeshes with one of a pair of pinions 43, 44, carried by a shift lever45, either of said pair being arranged to be brought into mesh with apinion 46, fast upon one of the wringer roll shafts. The constructionand operation of this feature of the device is fully set forth in ourcompanion application and requires no further description herein.

It is to be observed that the lid and gear mechanism carried therebymaybe raised without disturbing the remainder of the gearing. The flywheel and part of the operatin mechanism, including the motor, is locateunder the tub and out of the way. Other advantages are readily apparentfrom the above description.

We realize that various alterations and modifications of this device arepossible, without departing from the spirit of our invention, and we donot therefore desire to limit ourselves to the exact form ofconstruction shown and described.
